A South Hams council is being questioned after a post appeared on its official website of a Leave.EU video.

This is despite its own social media guidelines stating: “…official social media sites will not be used for political gain or campaigning”.

At the moment, it is unclear who posted the video on Dartmouth Town Council’s Facebook page on Monday evening. But the council’s guidelines state: “… social media sites are controlled and managed by the elected chairmen/vice chairmen of specific committees, the mayor/deputy mayor and clerk to the council, to be named as the communications team”.

The guidelines add: “Staff and elected members should adhere to the staff/members code of conduct in their use of social media and be aware that breaches will result in disciplinary procedure.”

The town council said on Tuesday morning, in response to questions from Chronicle: "You are correct in assuming that this is in contravention of our social media policy."The offending video was removed as soon as its presence came to our attention and the perpetrator has had posting rights withdrawn."

Leave.EU, a vehement anti-European Union campaign group, was co-founded by Arron Banks, one of the largest donors to UKIP until he was suspended from the party earlier this year.

The Brexit-backing millionaire businessman is being investigated by the elections watchdog over his donations in the EU referendum last year. The Electoral Commission has announced that it will look into whether Banks committed offences over donations or loans made to campaigners during last year’s referendum vote.
